Sure. Insurance is just a way of pooling risk. If you have enough money you don't need it. If you're an average risk, you save both the insurance company's profit and the tax you'd have to pay on the money you'd have to make to pay them.
A normal person has maybe ~$70k to lose if they get seriously ill or injured without insurance.
You have millions to lose.
I'm not making a moral judgement. It just seems crazy that you'd risk losing so much money just to avoid an expense that had to have been a rounding error to you at the time.
